What is the history of the popularity of lemons
The origins of lemons are a mystery, and it is widely believed that they originated in northern Burma and China. A study of the genetic origin of the lemon suggests that it originated from the hybridization of the citron and the bitter orange. According to Jewish historian Flavio Josephus, Jews in Jerusalem in the 90s B.C. threw lemons at errant priests on a certain holiday.
Jews traditionally used citrons rather than lemons. In ancient Rome, lemons entered Europe from southern Italy no later than the 1st century A.D., but the cultivation of lemons was not successful at that time. Around the 7th century AD lemons were introduced to Persia, Iraq and Egypt.
The first written reference to lemons is in a 10th-century Arabic work on agriculture, and at that time lemons were also used as horticultural plants to decorate Islamic gardens. Between 1000 and 1150, lemons were widely transported throughout the Arab world and the Mediterranean.
